Dehumidifiers are relatively low-maintenance appliances, but they aren't maintenance-free.
The following simple tips will help you keep your portable dehumidifier in excellent working condition and extend the product's life:
1. Review Your Owner's Manual
Maintenance tips will vary based on specific brands and models. Review your owner's manual for recommendations and requirements concerning placement, air filter cleaning, and draining.
2. Properly Place Your Dehumidifier
To get the best results from your dehumidifier, make sure you:
- Avoid Obstructions: Most models suggest at least 6-12 inches from walls and furniture to ensure proper air intake and exhaust.
- Place on a Level Surface: It's imperative to place your dehumidifier on a level surface.
- Close Doors and Windows: Keep outside air from entering the space to avoid high energy costs and overworking your dehumidifier, which will shorten the motor's life.
- Maintain Room Temperature: Dehumidifiers work best in rooms 55 degrees F and higher, so if you're using a dehumidifier in harsh environments, consider a specialized dehumidifier such as a commercial-grade desiccant dehumidifier designed for those spaces.
3. Clean the Condensate Bucket Frequently
You should clean the condensate bucket regularly with vinegar, water, and disinfectant to avoid mildew or mold growth. Even if it looks clean, occasionally clean it with soapy water and ensure it dries completely before using it again.
4. Don't Short-Cycle the Compressor
Avoid turning your dehumidifier off and back on immediately. After powering off, wait at least 10 minutes before turning the dehumidifier back on. The elapsed time will allow the pressure in the system to equalize and prevent damage to the compressor or tripping your circuit breaker.
In addition, short-cycling your dehumidifier leads to less efficient moisture removal because fully evaporating excess moisture takes longer. One way to avoid this is to purchase a dehumidifier with an automatic delayed start function to protect the compressor from damage.
5. Inspect the Condenser Coils for Frost or Ice Build-up
When your dehumidifier operates in cooler temperatures, the condenser (or cooling) coils may develop frost or ice build-up, which can interfere with operation.
Some models now include an automatic defrost function, which shuts the unit off until the coils defrost before turning the machine on again. However, if you suspect that your dehumidifier is malfunctioning due to ice or frost build-up, there are a few steps you can take to check:
- Access the Internal Coils: Turn the dehumidifier off and unplug it first to access the internal coils safely.
- Look for Ice or Frost: Inspect the coils for any evidence of ice or frost build-up caused by the space being too cool.
- Run until Warm: Allowing the dehumidifier to warm will defrost the coils. If this does not work, consult the manufacturer for assistance.
6. Clean the Air Filter
Most dehumidifiers have a washable air filter to remove harmful airborne particles such as dust and other allergens from your indoor environment. Ensuring the filter is clean helps maintain healthy indoor air. You can rinse with water or use a mild, soapy solution to clean the filter. A replacement filter is usually available should yours become torn or damaged.
7. Clean the Air Intake and Exhaust Grilles
Dirty grilles can contribute to poor dehumidifier performance. Once each season, or more frequently depending on their condition, clean the grille that takes in the humid air and the grille that releases the dehumidified air using a vacuum brush attachment.
In Summary
Using these simple tips and the manufacturer's maintenance guidelines in your owner's manual, you can keep your dehumidifier in top-performing shape and ensure years of continued use.
